Open collector open emitter

WebThe open-collector output of a power supply is a method of control circuitry used to output the state (status) and other information of the power supply. The output of a power supply is controlled by an open collector to turn it on and off externally. With open-collector output, an external circuit is connected to the collector and emitter ...
